Synopsis

The remote Slackware Linux host is missing a security update to vim.

Description

The version of vim installed on the remote host is prior to 9.0.2127. It is, therefore, affected by multiple vulnerabilities as referenced in the SSA:2023-328-01 advisory.

- Vim is an open source command line text editor. When closing a window, vim may try to access already freed window structure. Exploitation beyond crashing the application has not been shown to be viable. This issue has been addressed in commit `25aabc2b` which has been included in release version 9.0.2106. Users are advised to upgrade. There are no known workarounds for this vulnerability. (CVE-2023-48231)

- Vim is an open source command line text editor. A floating point exception may occur when calculating the line offset for overlong lines and smooth scrolling is enabled and the cpo-settings include the 'n' flag.
This may happen when a window border is present and when the wrapped line continues on the next physical line directly in the window border because the 'cpo' setting includes the 'n' flag. Only users with non- default settings are affected and the exception should only result in a crash. This issue has been addressed in commit `cb0b99f0` which has been included in release version 9.0.2107. Users are advised to upgrade. There are no known workarounds for this vulnerability. (CVE-2023-48232)

- Vim is an open source command line text editor. If the count after the :s command is larger than what fits into a (signed) long variable, abort with e_value_too_large. Impact is low, user interaction is required and a crash may not even happen in all situations. This issue has been addressed in commit `ac6378773` which has been included in release version 9.0.2108. Users are advised to upgrade. There are no known workarounds for this vulnerability. (CVE-2023-48233)

- Vim is an open source command line text editor. When getting the count for a normal mode z command, it may overflow for large counts given. Impact is low, user interaction is required and a crash may not even happen in all situations. This issue has been addressed in commit `58f9befca1` which has been included in release version 9.0.2109. Users are advised to upgrade. There are no known workarounds for this vulnerability. (CVE-2023-48234)

- Vim is an open source command line text editor. When parsing relative ex addresses one may unintentionally cause an overflow. Ironically this happens in the existing overflow check, because the line number becomes negative and LONG_MAX - lnum will cause the overflow. Impact is low, user interaction is required and a crash may not even happen in all situations. This issue has been addressed in commit `060623e` which has been included in release version 9.0.2110. Users are advised to upgrade. There are no known workarounds for this vulnerability. (CVE-2023-48235)

- Vim is an open source command line text editor. When using the z= command, the user may overflow the count with values larger than MAX_INT. Impact is low, user interaction is required and a crash may not even happen in all situations. This vulnerability has been addressed in commit `73b2d379` which has been included in release version 9.0.2111. Users are advised to upgrade. There are no known workarounds for this vulnerability. (CVE-2023-48236)

- Vim is an open source command line text editor. In affected versions when shifting lines in operator pending mode and using a very large value, it may be possible to overflow the size of integer. Impact is low, user interaction is required and a crash may not even happen in all situations. This issue has been addressed in commit `6bf131888` which has been included in version 9.0.2112. Users are advised to upgrade.
There are no known workarounds for this vulnerability. (CVE-2023-48237)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Upgrade the affected vim package.
